How to Beat the AI Agent

The AI agent is tight, honest and readable. Attack its blinds, keep betting when it only calls, and fold when it raises after the flop.

By Kevin Swinson, with ClaudettePart 16Game 990110For players

Since then: Jeff played the agent a fourth time. All four of his matches are in Part 17.

We sat the agent at a six-seat Robot Wars table with five of the site’s rules bots for 50 hands (Game 990110). The rules bots spent the game shoving pocket pairs into each other for 200 chips at a time. The agent stayed out of every one of those fights and was the only seat that grew its stack by actually playing: +74 chips, on 15 pots won. It also wrote down its reason for every move, which tells us exactly how it thinks.

It never bluffs after the flop.

Every bet and raise the agent made after the flop was with a strong hand: three of a kind, then a full house. Before the flop is another story, as you’ll see below. But once the flop is down, believe its raises. When it just calls, it usually has nothing.

Cheat sheet

When the agent…What it usually meansWhat you do
Is in the small or big blindIt folds most hands, even when everyone else foldedRaise. Take the blinds every time.
Raises from the button or a late seatA steal with almost anything: K3, J6, T6Re-raise. It gives up when played back at.
Raises from an early seatA real hand, like AQ or QJGive it credit. Fold your weak hands.
Calls your flop betUsually no pair, hoping to hitBet the turn too.
Bets or raises after the flopA strong made handFold unless you’re very strong.

Five plays that work

1. Steal its blinds

The agent folded before the flop 32 times out of 45 decisions. From the small blind it threw away K6, T9, 8-4, 9-3 and 7-5, several times after everyone else had folded to it. A raise into its blinds will usually win them.

2. Re-raise its button steals

In late position it raises with hands like K3, J6, T6 suited and 9-6 suited, reasoning that it has “fold equity.” It doesn’t defend those raises. On hand 3 it opened K3 from the button, the big blind re-raised, and it folded at once.

3. Bet the flop, then bet the turn

This is its most expensive habit. Three times it raised before the flop, called a flop bet without a pair, and then folded to a turn bet:

That cost it 28 chips without ever seeing a river. If it only calls your flop bet, fire again.

4. Fold when it raises after the flop

This is the flip side of “it never bluffs after the flop.” On hand 19 it flopped trip sixes with 9-6 and raised three times into seat 6’s pocket fives. It made a full house on the river and won 91 chips, the biggest pot it played. Seat 6 kept betting into a player that only raises with the goods.

5. Read its early raises as real

From early position it folded AT, KT and J8, and folded QJ once. It raised only twice: once with AQ, and once with QJ. Holding the same QJ, it folded one time and raised the next. Either way, an early-seat raise from the agent is a good hand, not a steal.

Don’t get overconfident

The agent’s patience is real, and it beat the rules bots with it. It never put its whole stack at risk on a pair the way they did. When it finally had a big hand, it got paid.

It also explains itself well. Its reasons usually name its position, how many players are left to act, and what share of hands beat it. That makes it predictable, but it isn’t random or reckless. If you play it the way you’d play a careful human, folding when it bets and betting when it checks, you’ll do fine. If you play it like a slot machine, it will wait you out.

The fine print

These tips come from one 50-hand game, 45 agent decisions and only four pots it played past the flop. They match what we saw in three heads-up battles against my friend Jeff, a serious tournament player. But they’re a scouting report, not a proof.

The agent is also still being tuned. If it learns to bluff or to defend its blinds, some of this advice will go stale, and we’ll say so here.
