1. Why does it prefer suited Kx, Qx to open over suited connectors?

2. Why so much cold-calling out of the SB?

High rake sims will put high priority on getting preflop folds both to avoid rake and because on theoretical high rake environments you face more aggressive responses and need to block reraises. This makes high cards better than playable hands.

The SB thing is not so much theory but more so something ppl tell you not to do because its difficult and on high rake it doesn't add a lot of EV

In his example the SB thing is vs a minopen, which definitely is a thing.

1) Like aner0 said, suited Kx type hands block more raises/calls than something like 65s. Higher rake incentives placing more value on steals - compare the NL500 and NL50 solutions.

I'll add that you're also more likely to flop higher cards due to the bunching effect.

2) EPs tight range prevents BB from squeezing you off your equity too aggressively, which is the main thing preventing you from calling more. The raise/fold strategy you were taught is largely an old-school simplification.

Pricing is also super important as Brokenstars pointed out. Your pot odds are considerably better vs a min open. Compare SB vs EP between the General and General 2.5x solutions to see what I mean.

Great explanations!

For #2, you can also use the (free) "Simple Solutions" if you prefer no cold-calls in the SB.

These eliminate all cold-calls outside the BB, SB limps, 4bet all-ins, and donkbets on the flop. They're further from equilibrium but some users find these solutions easier to study.

Thanks for the responses Always learn something from you guys

Is there any merit to opening suited connector type hands over suited Kx/Qx/offsuit Ax because they are "easier to play postflop", or is that snake oil advice?

will be more profitable vs fish/passive players or people overfolding pre/under 3betting, etc.

Is the the first problem due to these Kx and Qx hands having better showdown qualities than typical middle to low suited connectors?

The SB will probably call more vs a 2x than say a 2.5x or bigger due to getting a better price to call?

Reduces the 3b frequency of the other players primarily.
