Decided to defend my hand vs. raise coz its very weird to raise on this board with Jx or 44, sizing is also very low.
Got some backdoors and overcards so i think its fine to defend vs. such small raise.

I would propably fold to any bet without catching Q/K, but i found my card so...

Im not really sure how to play. What you think - how strong is villains range in this spot, is his range polarized on flop? What range should i use to defend it?
