Maximum legal raise

400

That’s your call of 100 plus a raise of 300 on top.

How it’s computed

Start with what’s out there: 100 pot + 100 in bets.
Pretend you call first: add your 100 call, so the pot would hold 300.
The pot-limit rule: you may bet that whole amount on top — a raise of 300.
Total chips you push forward: 100 + 300 = 400. If it’s all called, the pot becomes 600.

The rule in one line

The most you can bet or raise in a pot-limit game is the size of the pot after your call. Handy shortcut when facing a single bet: 3 × the bet + everything else in the pot. The full theory, with worked examples, is in Pot-Limit Betting Mechanics.
