SB defense with KQs

[ChickenGeorge]

Titan Limit Hold'em, $0.50/$1.00 (Titan HH Converter by Kreatief)

Villain is 17.7/7.5/2.34 over 1k+ hands. His att. to steal is 21%, but in the last few sessions I played with him he had been stealing quite aggressively. I suspect he adjusted his blind stealing range but the stats weren't yet reflecting that due to the large sample.

Preflop cap worried me. When I hit TP2K I decided to take a WA/WB line with a b/f (instead of c/c) on the river.

Correct? Or is there a better alternative?

Thanks.
